Use the PS pitman arm. Aren't the input splines the same for both the standard & PS boxes?

No, they are not.
Manual box has a smaller pitman shaft, power boxes have larger pitman shaft. Can't put a manual pitman on a power box and vice versa.
OP just needs an A-body power box pitman arm

I know that the std and PS pitman arms are different that's why I said to use the PS pitman arm. Forgot to specify the input shaft when I asked if the splines are the same, I meant at the input shaft. Also, I changes out '72 std box for a S box and the only thing that I needed was the a-body pitman arm because the PS box was out of a 454 Impala and the PS pitman is different for the full size models, but the box is the same. No alternate coupling was needed.
